Description of collection and treatment systems:
Charlotte-Mecklenburg Utilities collects wastewater from an estimated 205,569 connections to
households and businesses throughout the county. Wastewater is collected and directed (via
gravity flow supported by sewage lift stations) to one of five wastewater treatment plants where it
is treated. An average of 80.3 million gallons of wastewater is treated and discharged each day.
More than 100 employees work to maintain 3,433 miles of collection pipelines and 72 sewage lift
stations throughout the county. The gravity sewer pipes in this system range in size from 8 inches
in diameter to 78 inches in diameter.
Each of the wastewater treatment plants provides primary, secondary and advanced treatment to
the waste stream. Large solid particles and inorganic materials are removed by screening and
settling. The wastewater is treated biologically to remove dissolved pollutants. Disinfection
reduces bacterial and pathogenic materials. Finally, the waste stream passes through sand filters to
remove very small particles that may not have been removed through the settling process.
II. Summary of System Performance
How did we do?
Utilities had 370 sanitary sewer overflows this year which by number is 24 more than last
year. However, the volume of wastewater that overflowed declined by 84 percent (from
2,296,207 gallons in fiscal year 2005 to 329,038 gallons this year). Stated another way,
approximately 9,585 gallons per 100 miles of pipe in the ground overflowed from the
collection system this year as illustrated by the table below. While overflows remain our
major focus, it’s important to note that this amount represents 0.00112 % of the total flow
transported, and that the Charlotte-Mecklenburg wastewater collection system
successfully delivered more than 99.998 percent of this community’s 29.3 billion gallons
of wastewater for treatment last year.

Utilities works 24 hours a day, 365 days per year to prevent and respond to overflows.
Crews prevent overflows by clearing pipes of tree roots and grease, as well as replacing
broken and aging pipes. Utilities has also increased its efforts to educate customers about
properly disposing of oils and grease.
Highlights
Charlotte-Mecklenburg Utilities celebrated some important milestones even as it took
numerous actions to prevent overflows and protect water quality through effective
wastewater treatment.
•
•
•
•
•
•
•
Our wastewater treatment plants met 99.62 percent of all permitted discharge limits.
Approximately 800 miles of sewer lines were cleaned (including repeated cleanings).
17.3 miles of sewer pipe and 1,830 manholes were restored or replaced.
McDowell and Mallard Creek wastewater treatment plants received Peak Performance Gold
Awards from the National Association of Clean Water Agencies (NACWA) for the calendar
year ending 2005. The plants had 100 percent perfect compliance with NPDES permit
requirements. Sugar and McAlpine Creek wastewater treatment plants earned NACWA Silver
Awards for outstanding compliance.
Plant expansions and upgrades continued at all five treatment facilities to enhance performance
and increase reliability.
Zero overflows occurred at wastewater treatment plants.
In its sixth year, our Grease Free Program inspected grease-handling facilities at 2,283
restaurants to ensure compliance with the city sewer use ordinance and protect the sewer
system from improper grease disposal. Forty-eight Notices of Violation and Compliance
Orders were issued. The following programs continue to increase: Educational training and
presentations (34), residential and apartment handouts / mailings (7,600) follow up visits (961),
use of billboards (12 posted), sewer-overflow (150) and complaint investigations (17).

Two pump stations were closed and seven stations were added so there are now 72 pump
stations serving low-lying areas. Staff performed 64 preventative maintenance tasks on pump
stations (not including routine maintenance).
The Phosphorus Reduction Project at McAlpine Creek was placed into operation on schedule
by February 2006. Construction of this upgrade began in Fall 2003.

McDowell Wastewater Treatment Plant is expanding from 6 mgd to 12 mgd. The first
increment of construction to increase capacity to 9 mgd will be completed during the fiscal
year.
Phase 2 of the Irwin Creek Relief Sewer project is under construction.
Briar Creek and McAlpine Creek Relief Sewer projects are in design / real estate and are
scheduled to begin construction in fiscal year 2007.
Major improvements continue at McAlpine Creek Wastewater Treatment Plant including
construction of the consolidated influent pumping facilities project (75 percent complete) and
primary treatment improvements and effluent filter rehabilitation project (56 percent
complete).
The Field Operations Division successfully combined the previously separate Water
Distribution and Wastewater Collection operations into one unit. The areas of response and
service are divided into four zones to effectively provide water and wastewater maintenance
and construction services throughout Mecklenburg county. Employee development and
training was utilized to assist the formerly separate groups in acquiring enhanced levels of
understanding of the other's operation along with improvements in technology to produce
optimized processes of completing work assignments. The combined effort through the "zone
response approach" allows the Field Operations Division to meet the needs of our customers in
an efficient manner whether a water or sewer concern.
Continuing Challenges
Wastewater Collection Challenges
The greatest continuing wastewater challenge in this community – and in others across the U.S. –
is sewage spills and overflows. During the fiscal year ending June 30, 2006, Utilities reported 370
sewage spills from the collection system totaling 329,038 gallons spilled (304,958 gallons reached
surface waters). Most spills were due to grease buildup and the presence of tree roots in pipes.
Other factors contributed to overflows, including vandalism, old and/or broken pipes and general
debris blockage.

23%
While spills are an ongoing challenge, it’s important to note the Charlotte-Mecklenburg Utilities
wastewater collection system successfully delivered 99.998 percent of this community’s 29.3
billion gallons of wastewater last year. Our crews work 24 hours a day, 365 days per year to
prevent and respond to overflows.
Grease and other blockages that lead to sewer overflows are cleared by Utilities crews, using metal
rods and/or truck-mounted water jets. If damaged pipe or other infrastructure is discovered it is
repaired. The spilled sewage can sometimes be captured and pumped back into the sewer system.
Inspection crews and our customers find overflows. Reports of overflows where 1,000 or more
gallons reach surface waters are distributed to the media in an effort to notify the public. A legal
notice is posted when overflows of 15,000 gallons or more reach surface waters. Crews also use
door hangers to notify customers when appropriate.
Charlotte-Mecklenburg Utilities continues its excellent sewage spill response record. Our
wastewater collection staff response time averaged 43 minutes to all overflows as of June 30,
2006. Staff responded to over 80.8 percent of the spills in fewer than 60 minutes. This compares to
a state response standard of 120 minutes or less.
The five-year moving average now stands at 370 collection system spills per year (from FY2002 to
present- FY06).
Utilities continues to identify and correct grease, tree root and rain related overflows. Odor issues
in the collection system are improving but challenges remain.
Wastewater Treatment Plant Challenges
Charlotte-Mecklenburg Utilities five wastewater treatment plants met 99.62 percent of all
discharge limit tests set forth by our NPDES permits but our commitment is 100 percent
compliance. Staff continues to improve maintenance capabilities and overall performance. Major
rehabilitation and improvement projects help maintain compliance. Future upgrades and
expansions are being added.
During this fiscal year there were 27 permit limit violations. Of the 27 violations, 22 of
the violations were due to an illegal discharge of copper by a local industry into sewer
lines leading to the Irwin Creek WWTP. Investigation by Utilities staff led to the
discovery of the offending industry. They were ordered to cease and desist discharging
wastewater and the sewer pipe from the industry was plugged so no further discharge
could occur.
Including the copper violations caused by the illegal industrial discharge, the treatment
plants were in compliance 99.62% of the time. Without the copper violations the plants
would have been in compliance 99.93% of the time.
Our pretreatment program has identified, permitted and is regulating large industrial users to keep
unsuitable discharges out of the wastewater system. While industrial compliance is extremely high
in Charlotte-Mecklenburg, identifying other potentially hazardous discharge sources is an ongoing
challenge. In FY06 expansion of the trunkline monitoring program continued, enabling Utilities
pretreatment staff to closely observe what industrial and commercial customers discharge into the
sewer network and to identify potential problem areas to protect the collection system and plants.
The sections following this page – Sections IIA and IIB -- detail all spills from the collection
system and plants, along with plant permit limit violations and monitoring and reporting
violations. Section IIA includes spills for the fiscal year ending June 30, 2006 and is separated by
month. These include size of spills, their cause and descriptions of any known environmental
impact.
The second section, Section IIB, represents NPDES reporting and monitoring violations and is
separated by plant.

The weekly average limit for copper was violated every week in November and the
daily maximum limit for copper was violated on four (4) days. An investigation to
locate the source of the copper that was causing the violations was started as soon
as the violations were noted.
None
December,
2005
The weekly average limit for copper was violated in the first and third weeks of the
month. The daily maximum limit was in complinace this month. An investigation as
to the source of the copper was continuing through this time and the copper
concentration coming into the plant was dropping.
None
MONTH
January, 2006
In the last week of January the weekly average copper limit was exceeded again.
The daily maximum limit for copper was met all month. When the copper started in
the influent of the treatment plant started going back up, increased investigation
was started, the hours of operation at the septage receival station were reduced
and every tank of septage was sampled. All of the SIU's into the plant had been
investigated and the source of the copper had still not been found.
None
February, 2006
The weekly average limit for copper was exceeded the last three weeks of
February. The daily maximum for copper was in compliance all month. By the end
of February an in depth investigation involving all of the personel in the pretreatment
program was started. This investigation started with the mapping section in
Charlotte Mecklenburg Utitlies Engineering Division developing detailed maps of the
sewer collection system through out the Irwin Creek Basin, and also included the
Field Operations Division with help in locating and sampling throughout a colletion
system consisting of 354 miles of sewer lines.
None
March, 2006
The effluent copper limit weekly average was exceeded in three of the four weeks in
the month of March. The copper daily maximum limit was exceeded on four of the
six days copper was sampled. During this month the copper level into the plant
increased and the sampling through the trunkline of the system was increased
significantly and very rapid turn around times (TAT's) were initiated by our in-house
lab to the facilitate moving through out the system and determining where the
copper was coming from. The discharge was not daily, but the Sytem Protection
personnel were able to find the source. System Protection went to the facility with
the Charlotte Mecklenburg Police Department on 3/31/06 and issued a cease and
desist order to the company that was discharging the copper and their sewer
connection was disconnected. After 4/1/06 the influent level for copper started
dropping significantly and has returned back to normal and no further violations of
the copper limit have occurred.

cfu/100 ml. This exceeded the daily maximum fecal coliform
limit of 1,000 cfu/100 ml. This occurred due the the UV unit

Sugar Creek WWTP failed the quarterly toxicity sample with
cerio daphnia in February at 78.3%. The permit limt
requirement is to pass at 90% or higher. The same time the
toxicity sample was collected for cerio daphnia another
sample was collected to test the toxicity on flat head
minnows. This test passed at 100% of the effluent.
Subsequent toxicity tests for cerio daphnia were collected in
the next three months and all of the samples passed at
100%. We were not able to determine why the original
None
sample failed.

There was an inadvertent release of sodium hypochlorite into
the activated sludge of the treatment plant. Due to this
issue, the effluent became very turbid - inhibiting the UV
disinfection unit. This resulted in a violation of the daily
None
maximum limit for fecal coliform on 3/3/06.
